Using you digital camera, I will teach you how to take amazing pictures of lightning. All you need is a camera that you can change to exposure time. I have and love a Cannon PowerShot SD900. Its exposure can be set to up to 15 seconds.
Step 1Setting the Exposure
In order to take photos of lightning you need to determine how long you cameras exposure can be set, or if it even has the exposure setting. An exposure setting on a camera is telling the camera shutter how long to stay open. The longer the shutter is open, the more light that can be let in. Remember: it must be dark outside to take lighting photos like this, because you are letting light in and during the day the picture will just turn out white due to alot of light being let in.
Normally, when looking to find this exposure setting, you will need to change your cameras setting into Manual Mode. Then go into the menu and serch for where it says something like shutter speed or long exposure.
I have been using this on a Canon A710 IS to set aperture open time to up to 64 seconds. Allows Raw shooting and saving as well as many other features.
